T5 Vs. PC

Apparition · #1 09/07/2007, 02:52 AM

I know this is probably a basic question to most people, but I've had PC lighting for over 2 years and my current fixture is on its way out, so I'm wondering about upgrading to T5's. I guess my question is what are the strengths and weaknesses of each, which is better, a 55watt T5 or a 65watt PC, and how long do each bulbs last?

I keep just soft corals and LPS, so I don't need metal halide or anything. I currently have 4 65watt PC bulbs, two are 10k and two are actinics.

Thanks for any help or opinions.

Also, which T5 bulbs would you recommend if you recommend that 4x54watt fixture? There seem to be quite a few actinic choices. I currently use the Current USA 7100K Blue Power Compact bulbs.

from what ive gathered.
T5 bulbs need replacing about 12-18 months whereas PC bulbs are 6-12 months.

T5s have better penetrating characteristics and more PAR than PC bulbs, so the light is going deeper but keeping all its spectrum (think I got that right, correct me if im wrong plz)

Ive read that T5s run hotter than PC bulbs.

I have 96 watt 03 actinic blue. I like the color. I replace those about every 12 months.

Thanks for the info. I think I'll be switching to the T5's then.
